Accelerated Bayesian optimization for CNN+LSTM learning rate tuning via precomputed Gaussian process subspaces in soil analysis by Xiaolong Chen, Hongfeng Zhang, Cora Un In Wong, Zhengchun Song

“…PurposeWe propose an accelerated Bayesian optimization framework for tuning the learning rate of CNN+LSTM models in soil analysis, addressing the computational inefficiency of traditional Gaussian Process (GP)-based methods. This work bridges the gap between computational efficiency and probabilistic robustness, with broader implications for automated machine learning in geoscientific applications.MethodThe key innovation lies in a subspace-accelerated GP surrogate model that precomputes low-rank approximations of covariance matrices offline, thereby decoupling the costly hyperparameter tuning from the online acquisition function evaluations. …”

In situ electrochemical impedance spectroscopy of TiN-based hard coatings by Izabela Martinez, Božidar Matijević

“…Advancing hard coatings depends on incremental improvements driven by extensive experimentation, which could be significantly enhanced by a fast, reliable, and non-destructive method for assessing coating barrier efficiency. A previously developed electrochemical impedance spectroscopy (EIS) press-on cell with a chloride-free, pH-neutral paste electrolyte, originally validated on stainless steel, bronze, coated bronze, and Corten steel, was adapted to determine barrier effectiveness of four coating/substrate combinations (TiN/TiCN and TiN/TiBN on 42CrMo4 and 32CrMoV12-10 steels) produced via plasma-assisted chemical vapor deposition and characterized by glow discharge optical emission spectroscopy and scanning electron microscopy (SEM). …”
